    It might be wise to do the flywheel bolts also. Bigger injectors are needed also if you dont already have them.

    I have a stage 3 w/ 8350 limiter. The mid-range punch is much increased also.

    That is a good and solid set of mods you have listed but do not go with the bigger wheel if you plan to only run 48lb injectors. You will need to add a bunch more fuel that isn't capable of delivering. When I was data logging, I ran out of 48lb injectors even with stock X (195) wheel. So a 137+4 is out of the question (unless you plan to roman candle mod).

    So I recommend stay the same till you are ready to do all at same time. Same goes for the flywheel bolts as mentioned above. I've said this before and I'll say again...you can do flywheel bolts now while motor is together with all its parts or do it later when motor is in pieces. The outcome depends on your wallet and reading comprehension.

    ok, i have been thinking about the flywheel bolts, i really should do them, do you think it would be wise to just scrap the 137 idea and just go with the 127 wheel and deal with 12 pounds instead of 15?

    Pickup a stock xcharger which will give you a nice boost over 215 ..then when you're eventually ready for 137+4 it's a simple wheel swap.

    to me it makes no sense for a stock x charger, it puts out 10 pounds, i can go with a 127 wheel and have 12.5 pounds. or the 137=4 wheel with a 260 front cover and push out 5 pounds more boost then a x charger for less money.

    The 137+4 with Fizzle IC is an outstanding and reliable setup and thats still my vote.

    And FYI, I've made 13.6psi with a stock x-charger...you just need to be willing to spin it to win it

    If budget doesn't allow, the ET 127+3 is a great little wheel (and you keep same front housing). I don't have any real world data but from all the old articles I've read, the baby wheel should just edge out the stock x wheel...

    im takefull for your knowledge and time, and fully understand you. i can do the 137+4 with 260 cover for around 850. and i would have 12 to 15 pounds depending on rpm, im spinning 8350 now, but plan on 8800, from what i read on here, i can use the stock injectors which they can be maxed out, and can not be maxed out, depended on who is talking about it,

    Up to you, just giving you another possible option.

    You can pickup xcharger wheel for 1/3 the cost of 127+4. You would also need the front housing but if you're sure you're going 137+4 later on you'll need it either way and you'll still be under 127 wheel cost.

    Boost, you're comparing xcharger 10 PSI at stock RPM, well 127 does 10 PSI at 8100 ..spin it up to the same levels as that 127 will need to produce 12.5

    It's just an option, both will be nice improvement over 215
